Definitions

  • the present invention relates to a method for marking products with transparency, in particular multiple glazing, and in particular laminated safety glazing mainly used in construction, as well as glazing marked and made identifiable by this process according to the description below. below.
  • marking in common use, is intended to designate the inscriptions, possibly figurative, used to make an industrial product identifiable in order to trace its origin without fail.
  • the marking could be carried out in several relatively close places, so that the identification mark always appears on the glazing, even if the latter is cut into elements of sizes and configurations.
  • a main object of the present invention is the marking of transparent or at least translucent glazing allowing the industrial production of glazing, preferably laminated, which can then be identified unequivocally and without the dimensional limitations mentioned above.
  • the desired marking is carried out by affixing at will a succession of marks, preferably at a determined step, with a composition, and in particular an ink, which leaves a deposit practically invisible in normal lighting, but that the it can be made temporarily visible by fluorescence so as to identify the mark if the glazing is subjected to radiation using a source emitting such radiation and under suitable ambient lighting conditions.
  • an ink composed of substances having a refractive index very close to that of glass and intermediate layers of polyvinyl butyral, if not equal, so that invisibility is obtained under the various lighting conditions, by example in grazing light, when the glass surfaces are wet, etc ...
  • the marking can be carried out by different means using as indicated a suitable ink, for example using a stamp or a printing roller machine mounted on a suitable frame and moved continuously parallel to the surface of the glass for printing identification marks or signs.
  • the marking will be affixed on one of the internal faces of the transparent faces, before assembly.
  • the various layers of the glazing are obviously represented in a thickness that is significantly increased compared to its surface dimensions.
  • the laminated glazing consists of at least two external glass sheets 10 and 12 assembled by an adhesive interlayer 14 generally made of polyvinyl butyral.
  • the desired marking is carried out by printing on one of the faces of the glass sheets facing towards the inside of the glazing, for example on the face 10a of the sheet 10.
  • these marks shown schematically in FIG. 2 by groups of capital letters will be arranged, preferably, but not necessarily, regularly over the entire surface of the glazing, for example in rows or columns to obtain, however it is cut according of its processing dimensions, that the identification marks are present on the various parts originating from the cutting.
  • the mark will be made with a completely transparent ink in daytime or artificial lighting since the laminate is observed in transparency.
  • drawings or identification signs are drawn in dotted lines in Figure 1.
  • Wood light or black light is also known: it is the light from the arc of mercury enclosed in a quartz tube, filtered through a thick nickel oxide glass suitable; it belongs to the ultraviolet domain and has an intensity peak around 3650 ⁇ .
  • fluorescent inks can be of various types well known in the art.
  • these inks can consist of a solution of rosin of very high (clear) titer in solution in butyl and or benzyl alcohol with the addition of a small amount of a known fluorescent substance, for example, pyrene. , anthracene, rhodamine B, eosin.
  • ethylcellulose is added to increase the adhesive power of the deposit.
